SPECIFICATION forming part of Letters Patent No. 645,845, dated March20, 1900. Application filed April 4,1898. E5erla1No.676,33. (nan-man.)

To all whom it. may concern:

Beit known that I, STEPHEN D. BARNETT, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Binders for Documents,850.; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

The object of this invention is to provide a binder or clasp for filesof papers and small bundlessuch as drummers samples, &c.

which will be more conveniently and easily manipulated and to secureother advantages and results, some of which will be hereinafter referredto in connection with the description of the working parts.

The invention consists in the improved clasp orbinder and in thearrangements and combinations of parts of the same, all substantially aswill be hereinafter set forth, and finally embraced in the clauses ofthe claim.

Referring to theaccompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 is a transverse section of a bundle or file having my improvedhinder or clasp. Fig. 2 is a plan of the construction illustrated inFig. 1; and Figs. 3 and t are perspective views of the two metallicclasp members adapted to receive the opposite ends of a binding web ortape, the third member of the device.

In said drawings, a indicates the said tape or web, which is a fiattextilefabric adapted to present a comparatively-broad surface to thebundle or file to prevent injury tothe same. The broad surface of theweb or tape also serves in securing a firm binding-contact of the saidtape with one of the metallic clasp members or sections, as will behereinafter described. At one end of said web or tape in the preferredconstruction is permanently attached a broad hook b, which is preferablyof metal, and thus rigid and strong to resist the draft brought thereonin binding the articles of a bundle together.

tional bearing of one part on another.

The hooked member 29 is provided with a bar b, around which the tape islooped and fastened and parallel with said bar, with the hook b, adaptedto engage the cross-bar c of the second rigid frame 0 of the clasp. Thesaid frame a is made A-shaped, viewed endwise, and has three parallelbars a c" 0', the central bar 0 lying at the angle in the frame and theother two at the opposite longitudinal edges of the same. These barsform narrow slots 0" a through which the tape is that having the hookedmember is passed 1111-- derneath the bars 0 c, then up over the latter,and is then returned, passing beneath the said bar 0', between it and anadjacent portion of the tape, the said tape being thus doubled on itselfand having a broad fric- The tape is then placed around a file orbundle, as shown. By hooking the member 19 upon the bar of and thendrawing hard on the free end a of the tape the bar 0'' is brought downupon the upper portion of the doubled tape, pressing one layer againstthe other and forming a lock such as will prevent slipping orunloosening.

It will be noticed that the central bar a" is elevated very considerablyabove the plane in which the bars 0' 0' lie, and thus I secure a verystrong leverage,- the draft upon the bar 0" serving to force the bar 0down very hard upon the looped tape, whereby the up per and lower partsof said looped end of the tape are brought into very strong frictionalcontact, serving to lock the tape to the buckle with greater firmnessand security.

The bar 0" is provided with acentral lip or finger portion c, which alsoforms an angle when the member a is viewed in side elevation. the fingerbeing inserted beneath, as indicated inFig. 1, and thus when it isdesired to unloosen the clasp by simply raising the finger-piece andturning the member 0 pivotally on the barb, lying in the hook I), thebar 0" is lifted from the doubled tape, so that the latter runs over thebar 0" and is released from binding relation. When desired, the

This extends up so as to admit of file can be again bound tightly bysimply hooking the clasp members and drawing on the free end of thetape, as will be understood.

I am aware that various changes may be made in my improved'fastenerwithout departing from the spirit or scope of the invention. Theconstruction thus provided is simple and effective and especially usefulwhere the goods are sold in large quantities for free distribution asadvertising media.

Having thus described the invention, what I claim as new is- 1. Thecombination with the tape, having the hook fastened at one end, of aclasp memher a, /\-shaped taken endwise, and having
